Intensive land transformations which 17 is common in Transcaucasia, resulted in loss of natural habitat and population decline of the 18 species. One of the method for ex situ conservation is seed banking. Cryopreservation in liquid 19 nitrogen (LN; -196°C) is particularly of interest as it allows safe preservation of valuable plant 20 genetic resources. However, the feasibility of seed cryopreservation is related to their 21 desiccation tolerance and intrinsic composition. In this study, we examined the physiological 22 P. fraxinifolia seed traits from which desiccation tolerance is unknown or controversial and 23 their feasibility to cryopreservation,. Additionally, we tested stratification methods for 24 dormancy assessment. Results showedDraft that seeds survived desiccation to a 2.8% seed moisture 25 content (MC) and germinated in 64% . Stratification at temperature 3°C for 8 weeks was proven 26 to be both fast and effective. For cryopreservation, seed MC ranging between 2.8% and 18.1% 27 was determined to be safe. There was no difference in seedling emergence in seeds stored for 28 one year regardless of the storage temperature (-3°, -18° or -196°C). Based on our results, P. 29 fraxinifolia seeds can be classified as orthodox. This study demonstrates for the first time the 30 feasibility of cryopreserving P. fraxinifolia seeds. 31 Keywords: seed banking, cryopreservation, biodiversity, critical moisture content, Georgia 32 2 https://mc06.manuscriptcentral.com/cjfr-pubs Page 3 of 29 Canadian Journal of Forest Research 33 Introduction 34 The conservation of plant genetic resources is an established and globally recognized priority 35 because the variability of species is fundamental to forestalling their extinction. It is estimated 36 that there are more than 300,000 species of land plants, all of which are essential for the proper 37 functioning of local ecosystems (Corlett 2016). However, many populations of plants are 38 currently threatened by loss, fragmentation and degradation of habitats as well as 39 overexploitation, invasive species and climate change (Groom et al. 2005). Conservation 40 programs for threatened species can follow a variety of criteria, i.e., economic value, ecological 41 value or species uniqueness. One of the unique and irreplaceable parts of the plant kingdom is 42 relict trees. These surviving remnants have been present on the Earth for millions of years, 43 representing evolutionary processes andDraft outlasting environmental, biogeographical and climate 44 changes. Despite their continued existence over millions of years, they usually retain a narrow 45 distribution in so-called refugia (Maharramova et al. 2017; Kozlowski et al. 2018) such as 46 Hyrcanian area in the North Iran. The unique ecosystems of Hyrcanian Forests along with plains 47 around the Black Sea (Colchis Forests) are one of the most valuable biosphere genetic resources 48 in the World, which are a shelter of many relict species such as: Parrotia persica (DC.) C. A. 49 Mey., Gleditsia caspica Dest., Zelkova carpinifolia (Pall.) K. Koch. and Pterocarya fraxinifolia 50 (Poir.) Spach. (Naqinezhad et al. 2018). 51 The possibility of in situ conservation has its limitations. A holistic approach to 52 conservation is often difficult to fund and maintain (Diamond 1989), therefore, ex situ 53 conservation, such as seed banking, seem to be most suitable for seed bearing species, as it 54 provides inexpensive and effective long time strategy (Bewley et al. 2013; Zaritzky 2015). The 55 viability of stored seeds depends on the seed moisture content and storage temperature 56 (Vertucci and Roos 1990). Seed storability at low temperature depends on its desiccation 57 tolerance, as access water can crystallize and cause intracellular damage (Wesley-Smith et al. 3 https://mc06.manuscriptcentral.com/cjfr-pubs Canadian Journal of Forest Research Page 4 of 29 58 2014). The practical categorization proposed by Roberts (1973) and then supplemented by Ellis 59 et al. (1990) considers three categories of seeds divided on the basis of their desiccation 60 sensitivity: orthodox (seeds tolerate desiccation below a 5% moisture content, MC, fresh- 61 weight basis), recalcitrant (seeds that do not tolerate desiccation), and intermediate (seeds that 62 exhibits characteristic of both former categories i.e. seeds that tolerate moderate desiccation but 63 lose viability during subsequent storage at subzero temperatures). However, careful study of 64 seeds physiology is important; seeds storage behavior is often more complex as cellular 65 response on water and temperature thresholds create more in-between responses (Walters 2015). 66 Cryopreservation in liquid nitrogen (LN, between -130 and -196 °C) represents a safe 67 and cost-effective option for the long-term storage of germplasm. In recent years, 68 cryopreservation has become a successful method for conserving unique (i.e., endemic, 69 endangered, and economically valuable)Draft species, both as vegetative tissues such as dormant 70 buds and shoot tips and generative organs such as seeds and embryos (Engelmann 2011; 71 Lambardi and Shaarawi 2017). For orthodox seed species, cryopreservation is an alternative to 72 traditional storage at -20 °C and is of particular importance for long-term storage (10 to 100s 73 of years; Reed 2008), and it is the only method for the long-term storage of intermediate and 74 recalcitrant seed species. Cryopreservation of the seeds of woody species has proved to be 75 effective in both orthodox and recalcitrant seeds in many tree species, such as Alnus glutinosa, 76 (Chmielarz , 2010a, ), Coffea spp. (Dussert et al. 1998), Prunus armeniaca (Malik and 77 Chaudhury 2010), Prunus padus (Popova et al. 2016) and others. Together with the ex situ 78 approach, cryopreservation has been successfully utilized in conservation programs for 79 herbaceous plants, such as Cosmos atrosanguinea (Wilkinson 2002) or Lomandra sonderi 80 (Menon et al. 2014). Cryopreservation together with modern biotechnology has been 81 implemented in the conservation programs of many national floras, such as those of Brazil 4 https://mc06.manuscriptcentral.com/cjfr-pubs Page 5 of 29 Canadian Journal of Forest Research 82 (Pilatti et al. 2011), Spain (González-Benito and Martín 2011), Australia (Ashmore et al. 2011) 83 and others. 84 In our study, we examined Caucasian wingnut (Pterocarya fraxinifolia (Poir.) Spach.) 85 of the walnut family (Juglandaceae) as a model relict tree species which belongs to the so-called 86 Arcto-Tertiary relict trees and grows in the lowlands and riparian habitats of the Southern 87 Caucasus, Anatolia and Caspian (Hyrcanian) forests of Iran, Georgia, Turkey and Azerbaijan 88 (Boratyński and Boratyńska 1975; Kozlowski et al. 2018). During the Oligocene and Miocene, 89 the species was widespread in the Northern Hemisphere, but due to climate cooling over the 90 last 15 million years, it became restricted to southern refugial areas characterized by a more 91 stable climate (Manchester 1987; Milne and Abbott 2002; Maharramova et al. 2017). In some 92 locations, the population growth of the species depends on individual clonal reproduction via 93 root sprouts, as natural regeneration viaDraft seeds is poor, and a majority of the seeds is empty (up 94 to 90%; Yilmaz 2015). Its populations are characterized by intermediate to low genetic diversity 95 (Akhani and Salimian 2003;

  • Development of a Synthetic Plant Volatile-Based Attracticide for Female Noctuid Moths
    Australian Journal of Entomology (2010) 49, 10–20 Development of a synthetic plant volatile-based attracticide for female noctuid moths. I. Potential sources of volatiles attractive to Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae)aen_733 10..20 Alice P Del Socorro,1,2* Peter C Gregg,1,2 Daniel Alter2 and Chris J Moore3 1Cotton Catchment Communities Cooperative Research Centre, Narrabri, NSW 2390, Australia. 2School of Environmental and Rural Science, University of New England, Armidale, NSW 2351, Australia. 3Animal Research Institute, Queensland Department of Primary Industries and Fisheries, Yeerongpilly, Qld 4105, Australia. Abstract This paper is the first of a series which will describe the development of a synthetic plant volatile-based attracticide for noctuid moths. It discusses potential sources of volatiles attractive to the cotton bollworm, Helicoverpa armigera (Hübner), and an approach to the combination of these volatiles in synthetic blends. We screened a number of known host and non-host (for larval development) plants for attractiveness to unmated male and female moths of this species, using a two-choice olfactometer system. Out of 38 plants tested, 33 were significantly attractive to both sexes. There was a strong correlation between attractiveness of plants to males and females. The Australian natives, Angophora floribunda and several Eucalyptus species were the most attractive plants. These plants have not been recorded either as larval or oviposition hosts of Helicoverpa spp., suggesting that attraction in the olfactometer might have been as nectar foraging rather than as oviposition sources. To identify potential compounds that might be useful in developing moth attractants, especially for females, collections of volatiles were made from plants that were attractive to moths in the olfactometer.

  • Wingnut (Juglandaceae)
    83 Wingnut (Juglandaceae) as a new generic host for Pityophthorus juglandis (Coleoptera: Curculionidae) and the thousand cankers disease pathogen, Geosmithia morbida (Ascomycota: Hypocreales) Stacy M. Hishinuma, Paul L. Dallara, Mohammad A. Yaghmour, Marcelo M. Zerillo, Corwin M. Parker, Tatiana V. Roubtsova, Tivonne L. Nguyen, Ned A. Tisserat, Richard M. Bostock, Mary L. Flint, Steven J. Seybold1 Abstract—The walnut twig beetle (WTB), Pityophthorus juglandis Blackman (Coleoptera: Curculionidae), vectors a fungus, Geosmithia morbida Kolařík, Freeland, Utley, and Tisserat (Ascomycota: Hypocreales), which colonises and kills the phloem of walnut and butternut trees, Juglans Linnaeus (Juglandaceae). Over the past two decades, this condition, known as thousand cankers disease (TCD), has led to the widespread mortality of Juglans species in the United States of America. Recently the beetle and pathogen were discovered on several Juglans species in northern Italy. Little is known about the extra-generic extent of host acceptability and suitability for the WTB. We report the occurrence of both the WTB and G. morbida in three species of wingnut, Pterocarya fraxinifolia Spach, Pterocarya rhoifolia Siebold and Zuccarini, and Pterocarya stenoptera de Candolle (Juglandaceae) growing in the United States Department of Agriculture-Agricultural Research Service, National Clonal Germplasm Repository collection in northern California (NCGR) and in the Los Angeles County Arboretum and Botanic Garden in southern California, United States of America. In two instances (once in P. stenoptera and once in P. fraxinifolia) teneral (i.e., brood) adult WTB emerged and were collected more than four months after infested branch sections had been collected in the field. Koch’s postulates were satisfied with an isolate of G.

Avsar and Tolga Ok Department of Forest Engineering, Faculty of Forestry, Kahramanmaras Sutcu Imam University, Kahramanmaras, Turkey. (Received : 24 March, 2003 ; Accepted : 30 June, 2003) Abstract : Caucasian wingnut (Pterocarya fraxinifolia (Poiret) Spach) is a relict tree species having limited natural distribution in Turkey. In this study, a new distribution of this species in the Kahramanmaras region was explained. This distribution occurs in Onsenhopuru and Yavuzlar villages and Yesilyore town of Turkoglu district, at elevations between 600 and 640 m along Orcan stream, and continues about 4 km. In this area, Caucasian wingnut had about 100 trees. This distribution area of the species, quite important for biodiversity, should be protected and the existing individuals should be evaluated as a gene resource. Especially vegetative reproduction of the species should be started and the seedlings obtained should be used at the margins of lakes and streams, parks and large gardens, avenues, boulevards, and streets in the region. Key words : Pterocarya fraxinifolia, Natural distribution, Ecological characteristics, Biological characteristics, Protection. Introduction province were investigated, and some important The genus Pferocarya contains 8 species ecological and biological characteristics of the species throughout the world. One of these species is Caucasian were determined (Avsar, 2001).
